Caloric Restriction & Healthspan

Does caloric restriction improve longevity?

Yes. Caloric restriction (CR) without malnutrition is one of the most studied interventions for lifespan extension.

Explanation

Animal studies consistently show that reducing calorie intake by 20–30% extends lifespan and delays age-related diseases. In humans, caloric restriction lowers inflammation, improves lipid and glucose profiles, and reduces oxidative stress — all markers linked to longevity.

The CALERIE clinical trial demonstrated that even moderate caloric restriction (~12%) improved cardiometabolic risk factors and reduced markers of biological aging.

Practical Emphasis: Focus on nutrient-dense whole foods to avoid deficiencies, while reducing overall calorie intake moderately and sustainably.

Takeaway (Action Tip)

Consider moderate calorie restriction as a strategy to slow aging and improve healthspan.
